We have already mentioned the concept of a sprite being an entity that is drawn and handled at a specific position on a screen. Essentially, everything we see in a game are sprites. There are exceptions, such as game controllers (which do not draw anything) and backgrounds (which are drawn in a different way), but we will talk about them later in the chapter.
So, this is the code for the Sprite class that extends GameObject:
public abstract class Sprite extends GameObject {
protected double mPositionX;
protected double mPositionY;
protected final double mPixelFactor;
private final Bitmap mBitmap;
protected final int mImageHeight;
protected final int mImageWidth;
private final Matrix mMatrix = new Matrix();
protected Sprite (GameEngine gameEngine, int drawableRes) {
Resources r = gameEngine.getContext().getResources();
Drawable spriteDrawable = r.getDrawable(drawableRes);
mPixelFactor = gameEngine.mPixelFactor;
mImageHeight = (int) (spriteDrawable...
